I don't even think Özil - or Cazorla for that matter - have to be the ones to add goals. I think we have four proven 15+ goal a season scorers already. Giroud and Alexis we can pretty much count on. Theo is 15+ if he can stay fit. Ramsey can hit 15 if he returns to last seasons form. In addition to them we have Ox, Wilshere and Welbeck who can all chip in with more goals than they are this year if they keep developing. Our fullbacks usually chip in with a few goals a season as do our CBs from set pieces. I would prefer Özil focus on being a 20+ assists a season player rather than trying to get him to score more goals which isn't really his natural style.
